S1 will remain relatively unchanged over a temperature range of -40° F to 180° F.

LOXONTM S1 One Component Smooth Polyurethane Sealant

LIMITATIONS

Not recommended for:

a) Porous substrates subjected to continuous water immersion.

b) Joints contaminated with grease, wax, corrosion, bitumen or cement laitance.

c) Horizontal joints in floors or decks where abrasion or physical abuse is encountered.

d) Special architectural finishes without proper testing.

LOXONTM S1 sealant should be dry tooled. Tooling techniques using solvents or soapy solutions are not recommended.

All surfaces must be evaluated for adhesion prior to use.

Not designed as a glazing sealant in which the adhesive bond to glass is exposed to sunlight. The user or specifier should establish that any application in glazing will not expose the glass bond to appreciable amounts of ultraviolet radiation.

The surface of LOXONTM S1 sealant, when exposed to UV rays and sunlight, will yellow and not retain its gloss.

This may occur within a few weeks after exposure. The change of color is limited to the surface layer of the seal and should not compromise the sealing properties of the LOXONTM S1 if the dimensions of the joint are proper and the sealant is otherwise properly applied. In areas where color retention is critical, please refer to LOXONTM H1.

LOXONTM S1 will remain tacky for a few hours and attract dust and dirt from the jobsite which may affect the appearance of the sealant. Check tack-free time to prevent dirt pickup. Dampness and porous substrates with high moisture will trigger extensive curing of the sealant within a very short period of time. This may cause an excess of bubbling and foaming within the sealant and at the bottom of the bead.

During the cure time of LOXONTM S1, do not expose to curing silicone sealants, curing LOXONTM H1, alcohol based materials or solvents, acids, or solvent-based materials.

Until the sealant is fully cured, do not expose the sealant to any mechanical stress. Uncured sealant will not respond properly to cyclic expansion and contraction of the joint specified for the cured sealant only.

LOXONTM S1 must not be used to seal narrow joints, fillet joints, and face nail holes.

Smearing and feathering LOXONTM S1 over joints is not recommended.

Lower relative humidity and temperature will significantly extend the curing time. Confined areas, deep joints and moisture barrier substrates may also extend the cure time.

TECHNICAL DATA:

LOXONTM S1 exhibits excellent weatherability when exposed to ultraviolet radiation, atmospheric hydrocarbons and extremes in temperature. Joints designed to accommodate 70% total joint movement will not affect the seal or adhesion bond.

Joints properly designed and sealed will extend and compress a total of 70% of the installation width with no more than 35% movement in a single direction.

Cured sealant can be painted with emulsion or synthetic enamel paints. LOXONTM S1 will be virtually unaffected by contact with water after cure on non-porous substrates.

On porous substrates, priming is recommended if the sealant will be subjected to prolonged periods of immersion.

PRECAUTIONS: IF THIS PRODUCT IS USED IN DIRECT

CONTACT WITH ANY OTHER SEALANT OR ELASTOMER

A COMPATIBILITY TEST MUST BE CONDUCTED, BY

PURCHASER OR USER, PRIOR TO ACCEPTANCE.

LOXONTM S1 SEALANT IS NOT COMPATIBLE WITH

OXIME CONTAINING SILICONE SEALANTS.

INSTALLATION: JOINT DESIGN AND PREPARATION

Joint design depends on a variety of factors, such as the maximum expansion and contraction of the substrate from thermal change. Recommended maximum joint width should not exceed 1-1/2" (1.50") (3.81cm) and the maxi-mum joint depth should not exceed ½” (0.500") (12.69mm).

Minimum joint width should not be less than ¼” (0.250") (0.34mm). The sealant depth should be ¼” (0.34mm) for joints ¼” in width. For joints over ¼” in width, depth should be ½ of the joint width but should not exceed ½” (0.500") (12.69mm) in depth. In order to obtain the recommended sealant mass, the joint should be filled with closed cell backer rod first, leaving the proper depth to be filled with sealant. Desirable backer rod materials are polyethylene or polyethylene non-gassing foamed rod. Do not prime or puncture the closed cell structure of polyethylene rod as bubbles could form and migrate to the surface of the curing sealant. The use of open cell backer rod is not recommended. In situations where joint depth does not allow for use of backer rod, bond breaker (polyethelene strip) should be used to prevent three-sided adhesion.

SURFACE PREPARATION:

Old sealant should be completely removed. Concrete and masonry surfaces must be free of foreign matter and contaminants. Dust and loose particles should be blown out of joints. A clean, dry, sound and uncontaminated surface is mandatory. Stone surfaces must be cohesively sound, dry and free of contaminants. Granite, limestone, marble and sandstone must be pre-tested for adhesion prior to sealant installation.

Mill finish aluminum may contain an invisible oil film or oxide. Clean with an appropriate solvent. The use of solvents may be hazardous to your health. Use only in well ventilated areas. KEEP AWAY FROM OPEN FLAME.

Read all labeling before use and follow solvent manufacturer’s recommendations and instructions for safe handling. Many high-performance coatings or unusual surface treatments may require abrasion of the surface with steel wool or fine emery paper during preparation.

a) Priming of masonry or other porous substrate joints is recommended only if the joints will be subjected to prolonged immersion. Joints subjected to intermittent immersion or vertical joints subjected to rain should perform without the need of a primer.

PRIMING:

Certain situations or substrates may require a primer.

Ensure compatibility before using primers. See primer PDS for details (SUPRIQD13).

6/2022 pg 2 of 4

c) LOXONTM S1 sealant is compatible with most coatings and treatments, but due to the vast numbers of, and types of surface coatings available, Sherwin- Williams recommends pre-testing LOXONTM S1 sealant on the surface in question. Follow manufacturer's recommended recoat times for application of LOXONTM S1 sealant to primers or treatments. Check primer or treatment for surface contaminants prior to application of sealant.

METHOD OF APPLICATION:

All surfaces must be structurally sound, clean, dry, and fully cured. A field adhesion (pull test) in test joints is recommended, before application. Apply LOXONTM S1 sealant in a continuous operation, using a professional grade caulking gun and positive pressure adequate to properly fill and seal the joint.

TOOLING:

LOXONTM S1 sealant should be dry tooled. Tooling techniques using solvents or soapy solutions are not recommended.

Tooling of freshly applied sealant is necessary for proper adhesion. Tool the sealant with adequate pressure to spread the sealant against the back-up material and onto the joint surfaces.If joint surfaces have been masked, remove masking tape immediately after tooling.

PAINTING:

Exercise caution if painting. When painting over LOXONTM S1 sealant with primers, top-coats or treatments, cracking or peeling of these coatings could occur because of joint movement. In general, oil-based paints are not recommended because of their relatively poor elastic properties and because of their potential interaction with the sealant chemistry, which may create non-curing conditions for the painted sealant. Do not paint over LOXONTM S1 sealant until it has fully cured. Cure is dependent on temperature and humidity and may take 7 or more days.

LOXONTM S1 sealant when applied in a typical 1/2" x 1/4" bead and backed with a suitable bond-breaker at 75°F and 50% RH, will be acceptable for painting with breathable coatings within 48 hours and non-breathable coatings after 72 hours. Warmer, more humid conditions will allow LOXONTM S1 sealant to cure more quickly and conversely, cooler and/or drier conditions will lengthen the cure time. A small test area is strongly recommended.

CLEANING:

Cured sealant is very difficult to remove. Excess sealant and smears should be dry-wiped from all surfaces while still uncured, followed with a commercial solvent such as xylol, toluol or methyl ethyl ketone. The use of these solvents (or other solvents) may be hazardous to your health.

KEEP AWAY FROM OPEN FLAME. Read all labeling before use, and follow solvent manufacturer’s recommendations and instructions for safe handling. Tool and application equipment may also be cleaned with the same solvents. The dried sealant can be removed by cutting with a sharp-edged tool;

thin films by abrading.

CAUTIONS

It is recommended that all surfaces be pre-tested with LOXONTM S1 sealant to determine if cleaning will be necessary to remove surface contamination. In the case of some exotic coatings, priming or other surface treatment may be necessary.

Performance Tips:

Prevent LoxonTM S1 from coming into contact with oil-based sealants, uncured silicone sealants, polysulfides, or fillers that contain oil, tar or asphalt.

LOXONTM S1 sealant will not adhere to previously applied silcone sealants.

Protect unopened containers from direct sunlight and heat.

In cool or cold weather, store container(s) at room temperature for at least 24 hours, before using.

LoxonTM S1 can be applied below freezing temperatures only if: substrates are completely dry and free of moisture, and clean.

Do not apply over freshly treated wood; treated wood must have been weathered for at least six months.

* Do not use in swimming pools or other submerged conditions where the sealant will be exposed to strong oxidizers/chlorine. Avoid submerged conditions where water temperatures will exceed 122˚ F (50˚ C).

Substrates such as stainless steel, copper, and galvanized steel typically require the use of a primer.

LoxonTM Quick Dry primer SUPRIQD13 is acceptable. LoxonTM Quick Dry primer SUPRIQD13 can also be used for Kynar 500 based coatings.

An adhesion test is recommended for any questionable substrate.
