Main Use
1. This product is mainly used as a synthetic raw material for high-softness, low-yellowing amino silicone oil fabric finishing agent. It is used as a secondary amino and tertiary amino double modified amino silane coupling agent. The finishing agent made with it can make the fabric have the advantages of softness, smoothness, bulkiness, elasticity, etc., and overcome the shallow The shortcomings of colored fabrics that are easy to turn yellow, the finished fabrics have better hydrophilicity (0.45 ammonia value is generally 9s on cotton), and the finishing liquid is not easy to stick to the roller.
2. Used as an additive or as a primer liquid for polyurethane, silicone, epoxy, nitrile, phenolic, acrylic and other coatings, inks, adhesives and sealants to improve the adhesion, corrosion resistance, and corrosion resistance of resin coatings. Weather resistance, boiling resistance and scrubbing resistance, extend the service life, and
improve the dispersion and bonding of the pigment and filler in the resin phase, which can greatly increase the crosslinking density of the product and provide better adhesion to the substrate.
3. As a secondary amino silane for the end-blocking modification of isocyanate, the reaction is mild and controllable. It is used for one-component, primer free polyurethane adhesives and SPUR adhesives. It provides good water resistance, weather resistance and resistance to many different substrates. Good adhesion of the material, reducing the content of free isocyanic acid, making the product more environmentally friendly
4. As an ammonia curing agent for epoxy modified silicone resin and epoxy resin.
