Specialties

with No Comments
According to the different resin systems and characteristics used by customers, we have developed some specialties that are including: conductive agent, hammertone agent, moisture scavenger, flavor shielding agent, catalyst, water-based PU thickeners, anti-settling agent, wax dispersion, anti-biocide agent and viscosity stabilizer, etc. These products will enhance the specificity and excellent performance of customer products.

Catalyst

Product

Composition

Application

Dosage

DBTDL

Dibutyl tin dilaurate

It is a high efficiency curing catalyst for polyurethane coatings, foams, adhesive and sealant. Promoter of the reaction of isocyanates with polyols to form polyurethene, and reduce cross-linking time.

0.005 - 0.3% based on    total formulation

DBCT-90

Amine salt of p-toluene sulfonic acid

It is a blocked curing catalyst used in baking paints especially for fully alkylated melamine which need strong catalyst. It can either lower baking temperature or shorten baking time. When added in baking paint, it shows better storage stability, lower viscosity, less gelation tendency. The deblocking temperature is over 90℃

0.5 - 2% based on  total formulation

DBCT-130

Amine salt of p-toluene sulfonic acid

It is a blocked curing catalyst used in baking paints especially for fully alkylated melamine which need strong catalyst. It can either lower baking temperature or shorten baking time. When added in baking paint, it shows better storage stability, lower viscosity, less gelation tendency. The deblocking temperature is 130℃.

Dosage

HT

High molecular weight silicone

Lower dosage produces coarse pattern. In contrast, higher dosage gets fine texture, however, compatibility and storage stability should be checked. Incorporation is made during let-down or color matching. Special care should be taken to avoid contamination to other products.

Dosage

RHEO S-20

Polyamide wax

It is a polyamide wax dispersion anti-settling agent which prevents pigment or filler settling and sagging.

0.3 - 2% based on  total formulation

RHEO W-50

Non-ionic polyurethane compound

Thickening behavior is not affected by pH value. To increase medium shear viscosity to improve flow and leveling and reducing roller spatter and brush marks.

Excellent resistance to bacterial degradation. Less influence on gloss and water resistance.

0.1 - 2% based on  total formulation

RHEO W-52TF

Non-ionic polyurethane compound

Environment-friendly. tin-free, low odor and solvent -free. To increase medium shear viscosity to improve flow and leveling and reducing roller spatter and brush marks. Excellent resistance to bacterial degradation. Less influence on gloss and water resistance.

Blocked aliphatic polyisocyanate

Product

Composition

Application

Dosage

BISO 7511

Blocked aliphatic polyisocyanate

It is used to formulate one component polyurethane backing paint, the curing temperature must above 130℃, higher temperature is shorter cross-linking time. After baking, the film hardness is stable no variation with time in one-component PU.

To substituted for melamine or amino resin (20 - 40%).

Viscosity Stabilizer

Product

Composition

Application

Dosage

VIS

Combination of special surfactant

It is an additive for stabilizing viscosity of air-drying and baking paint. It is also used to recover gelled paint to applicable viscosity.

Add 1 - 2% based on solid content of paint before grinding.

For already gelled paint, add 3 - 7% based on solid content of paint with sufficient mixing to achieve workable viscosity.
