Specifications
RLC-2935 Industrial MS Sealant
Description |
RLC-2935 industrial MS sealant is developed and produced with the imported MS-polymer resin raw material. This sealant inherited the advantages of polyurethane (PU) and silicone sealants as well as polysulfide sealants. Fast cured, no primer, can be painted, high quality joint sealant , ideal even for metal materials. It is uvioresistant, excellent weatherablity, corrosion
resistance, solvent free, isocyante free, silicon resin free and environmental protection product.
Characteristics |
a. Friendly to user and environment: no solvent, halogens, isocyanates, odorless
b. Can be painted
c. Easy to use at a wide range temperature, even in damp environment
d. High bonding strength, special for metal materials
e. Excellent weather proofing ability
f. Fast cure even at low temperature
g. Permanent elasticity after cure
h. Neutral curing, no pollution for stone, concrete
I. Medium modulus MS sealants,excellent overall performance.
Where to use |
(1) Bonding and sealing for car, train, truck and their ceilings.
(2) Aluminum or polyester adhesive in side and outside of the family car.
(3) Adhesive of Polyester component and the metal frame
(4) Adhesive of floor system
Elevator, containers, ships, metal construction, machinery, electronics, plastics, air conditioning,
clean room, ventilation equipment and other joint seal

Colors |
Standard color: black, white and grey.
We can also supply the other color according to the customer's requirement.
Storage |
It has a useable life of 12 months from the produced date when stored under dry and airy,27℃
or lower temperature conditions in the original unopened container.
Application |
Surface preparation
Clean all dirty, dust, loose particles by steel brush and clean all oily things with cleaning agent. All
former adhesive must be cleaned out by scraping, paring, friction, jet of strong air or suitable ways. Make sure the surface be clean, free of dust and grease
Priming
Commonly it is no need of primer.
Spreading
Spread the sealant on base material with enough pressure and thickness not less than 1 millimeter if for bonding. If it is used for sealing, extrude the sealant full of the joint. And then leave to cure.
Paintable Property |
It could be painted after dry with traditional method like epoxy or acrylic paints. The adhesive surface will take place reaction and soften if using high solvent content coating like luster enamel or high oily base coatings.
Coating should have similar tensile strength compared with adhesive in order to get best
appearance and property. Painting could be processed after 24 hours if thickness of adhesive is
less than 3 mm. Another, painted after 48 hours if thickness more than 3mm.
Handling Precautions |
1. Not contact sealant with food or cosmetics;
2. Not contact skin for long time about uncured sealant;
3. Rinse eyes with large quantities of water and seek medical check if sealant drops into eyes.
4. Not put sealant out of children
