Product introduction
AC-3168 is CoatOSil™ MP 200 Silane alternatives, AC-3168 is a silicone low polymer containing epoxy functional groups that can participate in film-forming reactions. It can be directly added to water-based or oil-based coating systems and maintains good hydrolysis resistance and storage stability. Special silane coupling agent. Also known as: adhesion promoter, cross-linking agent.
Physical and chemical properties
Appearance: colorless to light yellow liquid
Specific gravity: 1.03 g/cm2
Active ingredient: 100%
Viscosity: 30-100 Mpa.s
Application areas
Water-based and oil-based: surface treatment of epoxy, acrylic, alkyd resin paints and aluminum silver paste, copper gold powder and inorganic pigments and fillers.
How to use and precautions
Please test the optimal dosage, compatibility with resin and storage stability before use. The generally recommended dosage is 1 to 3% of the resin content.
Addition method:
1. Resin pre-grafting modification method: Since the inorganic pigments and fillers will participate in the reaction and snatching of the active ingredients of the additive, and the grafting reaction between 3168 and the resin requires a certain induction period, it is used in For high-pigment filler systems such as colored paints and matte paints, it can be used together with the co-solvent in the formula to fully stir and mix with the resin and then let stand for more than 48 hours, so that 3168 and the resin can fully complete the grafting reaction and then be used as a graft-modified resin. spare.
2. It can also be added directly during the paint making process, but it also needs to be tested after 48 hours before making a board.
3. For surface treatment of powders and metallic pigments, ethanol can be diluted and reacted directly with powders or inorganic materials.
Application characteristics
It has good compatibility with most common emulsion compounds such as water-based epoxy, water-based acrylic, and water-based polyurethane; it can react between the resin and the substrate or inorganic filler to form a chemical bond with strong affinity, thus improving the resistance to glass, aluminum alloys, and plating. It has good adhesion to substrates such as zinc plate, stainless steel, and plastic that are difficult to adhere to. It can also be used as an anti-swelling and anti-falling surface treatment agent for metal pigments such as zinc powder, aluminum silver paste, etc.
It can be grafted and modified with the carboxyl groups contained in the resin at room temperature, and it can also open the ring during the curing process to give the polymer an additional 1K cross-linking reaction. Using this principle of silane modification of resin and increasing polymer cross-linking density can significantly improve the drying speed, hardness, gloss, boiling resistance, salt spray resistance, acid and alkali resistance and other properties of the paint film.
Storage
Store in a cool, ventilated warehouse, away from heat and fire sources, and keep sealed and protected from light. It can be stored for 1 year from the date of production.
