    In the chemical session there is also such a group of highly skilled "Wu lin master", although they do not occupy half of the mountain, but with their own unique skills proud of the world, people dare not be small, they are - additives.
    people's enlightenment of additives is usually the catalyst, Jianghu people called "catalyst", it cleverly changes the chemical reaction in dexterous shape, and even out of the "dot stone into gold" mysterious legend.
    Although the rumors are too false, but have to admit that catalysts do occupy an extremely important position in the modern science industry, more than 90% of the industrial process has its presence, in the polyurethane industry, catalysts are also essential
    , polyurethane foam additives
    so-called "foam additives" are just a generalization, the reaction process to play a supporting role in the additives, can be classified in this category. Commonly used foam additives are generally catalysts, silicone oil (foaming agent), perforation agent, and other additives according to the needs of choice. As a polyurethane foam industry, Wanhua Chemical has developed a series of complementary additive products for raw materials to improve the solution.
    01, delayed amine catalyst
    delayed amine catalyst, its role is to adjust the reaction process, used to mold polyurethane foam, can extend the pre-flow time, shorten the late foam maturation time and improve the skin molding, so that polyurethane foam presents the best state, while reducing the defect rate of products.
    wanALYST® KC112 as a temperature-sensitive delay catalyst, can be used in epoxy, adhesives and composites and other fields to promote the rapid gel maturation of materials.
    02, silicone oil surfactant
    silicone oil surfactant, also called homogenizing foam agent, with two-parent structure, on the one hand to promote the system material polarity between different components of emulsification, increase capacity;
    WANALYST® SC815, WANALYST®SC870 is a molded high-rebound homogenizer product with the ability to stabilize foam and control openings, and help reduce the overall voCs of foam.
    II, coatings /ink additives
    additive products also have important applications in the field of coatings/inks, the main roles include preventing pigments from sinking or floating, promoting the formation of smooth and shiny surfaces, regulating the viscosity of coatings, promoting film attachment and curing, and giving special functions to coatings. In practical applications, because coatings, ink products are very complex chemical components of the system, of which the additive products are rich and diverse.
    01, dispersant
    WANALYST® DS360 dispersant: In the ester-soluble composite ink system, DS360 pairs of low- and medium-color carbon black, indistinct blue has a good dispersion and color display ability, significantly reduce the viscosity of the ink system, improve storage stability, avoid coarseness.
    WANALYST® DS190/191 Dispersants: For all kinds of polar industrial paint systems, organic pigments and carbon black have a good wetting, dispersion and adhesion effect
    02, leveling agent
    WANALYST® SC 603 silicone leveling agent: wood paint, industrial paint leveling agent, leveling effect and versatility is good, applicable to UV, solvent-based, water-based coating system, with excellent feel, scratch resistance and anti-shrinking perforation, is conducive to improve the paint film gloss and freshness, basically does not affect inter-layer adhesion.
    WANALYST® SC611 acrylic leveling agent: In solvent-based coating systems, it improves leveling, increases gloss and allows the coating to produce long-wave effects without affecting heavy coating and inter-layer adhesion, and is suitable for medium polarity and polarity systems.
    03, desolation agent
    silicone deblister is usually high surfactant, the role is to reduce the interface of the bubble surface, causing polyging, so that the bubble instability, and then burst;
    WANALYST® SC702 silicone desiccant: wood paint, automotive paint and other general-purpose leveling agents, with a wide range of resin system compatible, excellent de-foaming effect.
    WANALYST® SC730 acrylic desostase agent: can be used in wood coatings, buildings, floor coatings, etc., with excellent de-foaming, both auxiliary leveling effect, does not affect re-painting.
