Application:
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 and
tertiary amino group modified aminosilane coupling agent. The finishing agent
made with it can make the fabric have the advantages of softness, smoothness,
bulkiness, elasticity, etc., while overcoming the superficiality. The shortcomings of
colored fabrics that are easy to turn yellow, the finished fabric is relatively
hydrophilic (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.
Packing and storage:
1. Packing: 200KG/drum or other packing on request.
2. Stored in acool, dry place. Avoid direct light.
