| Description: | Deion: 3M ™ fights pollution coating and additives SRC - 220 is a kind of containing fluorine polymer solution, usable or water-soluble solvent for dilution (such as ethanol, ketones, glycol ether or DPM, ChanDing NMP, etc.). Of the diluted products can be used to porous surface infiltration cryoprotectants, protect the surface, make are less susceptible to infection of various dirt. SRC - 220 fluid can be as antifouling paint recipe for a variety of sexual additives, give antifouling properties. SRC - 220 already in the United States toxic substances control directory registered. Suggestion: used 3M ™ resistant to contamination coating and additives SRC - 220 can be diluted to 20 to 30 percent of concentration, used as permeability sealants, of the porous surfaces provide waterproof and defense oily protection, including cement, lime putty, no glaze ceramic tile, granite, marble, tablets and pottery, and so on. The coating is easy to use, dry quickly, long lasting, and do not change is processed surface appearance and permeability and other properties. SRC - 220 protectants still is had prevent mildew and fungal growth function. SRC - 220 can also used to be able to bear or endure corrupt sex additives, can be in 1 ~ 3% of dosage, used in all kinds of acrylic type and polyurethane type coating, increase of oil and water resistance and resistance to contamination sex. Standard physical properties: Appearance translucent solution Activity content (weight %) 20% Solvent DPM (5%) and water (75%) Viscosity < 30 CPS Density 1.1 g/ml VOC (ASTM 3960-89) < 2.4 g/l PH 7-8 The boiling point 100 ° C The vapor pressure 18 ° C mmHg @ 20 The rate of evaporation 1 water = 1 Floc point 93.3 oC > Stability under atmospheric at least one year. Frozen - thawing stability, before use restore to room temperature, before using mixing. Properties: Used for penetration protectants: 3M ™ SRC - 220 in water dilute to 20%, or in ethylene glycol ether ChanDing in dilute to 15% respectively, the Mexican SLATE, limestone and marble comparative experiments. Each protectants besmear 2 times, dry 24 hours. The surface of the use of hydraulic fluid, dirty oil, corn oil, fangdongye, mustard, grape juice, coffee, red wine, soy sauce and coke contamination, after 24 hours, stone template wash, sponge to wipe, dry. Each stained rating as follows: 0: without stains, 1: very light smear, 2: light smear, 3: moderate stains, 4: heavy smear, 5: in 1 hour penetrates into SLATE spots. For each sample performance rating summary, result see table 1. SRC - 220 effect will depend on the stone material properties and smear medium and decide. Table 1.

Add after SRC - 220 of coating on the surface (wood, cement, lime), dry 3 days. Then measured water and hexadecane the contact Angle. Results in table 2. Results show that adding 2.5% SRC - 220 after, can achieve greater water and hexadecane the contact Angle, thus increasing the size of water and oil resistance performance. Table 2.

When necessary, also can add surfactant and rheological agent. Used as antifouling additives: SRC - 220 can be as antifouling additives to join many coating formula, dosage is about 1 ~ 3%, specific amount and coating formulation of relevant components. Of course you must test its and coating properties such as the compatibility. storage SRC - 220 for repeated freeze-thaw stability. Shelves storage period for 1 year. SRC - 220 were classified as a harmless ministry, not flammable materials. | |
