Specialties
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.
| Product | Composition | Application | Dosage |
|---|---|---|---|
| Catalyst | |||
| 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℃. | 0.5 - 2% based on total formulation |
| Hammertone Agent | |||
| 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. | 0.05 - 0.5% based on total formulation |
| Conductivity Agent | |||
| C-75 | Quaternary ammonium compound | It is an effective auxiliary for reducing the resistance of paints that are sprayed electrostatically. It can be applied to various paint systems, such as alkyd melamine baking enamels, acrylic baking enamels etc. | 0.1 - 2% based on total formulation |
| Moisture Scavenger | |||
| MSC | Trimethoxymethane | Stabilizer for polyurethane coatings. It is used in isocyanate and hydrocarbon coating system as a moisture scavenger. Trials should always be carried out to determine the suitability if the product for the intended application. | 1 - 3% based on total formulation |
| Rheology Modifier | |||
| 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. | 0.1 - 2% based on total formulation |
| Blocked aliphatic polyisocyanate | |||
| 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%). |
| Matting Agent | |||
| PEW-10 | Wax dispersion | It is an unique matting wax dispersions with exceptionally matting as well as slip enhancement effect to the coating films. To improve smooth, transparent, lubricating and silky feeling surfaces. | 10- 20% based on total formulation for semi-gloss. |
| Viscosity Stabilizer | |||
| 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. |
