Cunninghamia lanceolata film-forming additives ester alcohol 12 is used in emulsioni paint is very important in a coalescence additives, with the increase of addition amount of emulsion minimum film-forming temperature gradually reduced.Fir film-forming additives ester alcohol 12 are widely used in latex, adhesive, architectural coatings, fir film-forming additives ester alcohol by particularly applicable to a variety of (meth) acrylate, styrene, vinyl acetate as raw material to synthesis of all kinds of latex, latex paint, water-based adhesives such as system.After film-forming effect and make paint with unique storage stability, flow property and adhesion, and can improve the gloss.
Cunninghamia lanceolata film-forming additives ester alcohol 12 basic attribute
Trade name: ester alcohol, ester, alcohol twelve
Chemical name: three, 3 - methyl - 1, 2, 4-trichlorobenzene e single isobutyric acid glycol ester
Add concentration: 5% to 10%, to achieve the best performance of emulsion paint depends mainly on the coalescence of additives concentration needed for minimum film-forming temperature of latex polymer hard than soft polymer polymer needs more coalescence additives, to achieve the same effect of coalescence.Try to match the emulsioni paint, according to the weight of the emulsion polymer solid, concentration of film forming additives best start from 5% to 10%.
Basic properties:
1, film forming additive ester alcohol. To improve the film forming performance of emulsioni paint, improve film weather resistance, scrub resistance, clean, can repair paint and improve the coating color, etc.
2, film-forming additives ester alcohol. Reduce the minimum film-forming temperature of latex paint.
3, film forming additive twelve ester alcohol hydrolysis stability is very good, can work with, including pH of high pure acrylic emulsion, all kinds of latex are used together.
Twelve to join emulsioni paint, film-forming additives ester alcohol, is absorbed on the latex particle, softening particles and cause better fusion in the painting.It will not be sucked into the porous matrix, but can be effectively coalescence latex particles.
5, film-forming additives twelve ester alcohol freezing point is very low, do not need special treatment in winter.
6, film-forming additives in the twelve ester alcohol easily mixed with emulsion, and at higher levels shall not affect the stability of the coating.
7, film-forming additives ester alcohol twelve is the strong solvents of emulsion polymer film-forming additives ester alcohol 12 application features:
1, is a good solvent, emulsion polymer can reduce the minimum film-forming temperature of polymer;
2, low solubility in water;
3, has certain volatile, film-forming process can play a role in the film, film after all volatile, not affect coating performance;
4, do not affect the stability of the emulsion.
Safety performance:
Cedar ester alcoholic WeiDu products, after skin contact rinse off with water and soap.Compared with ethylene glycol butyl ether and benzene methanol can be avoided due to long-term exposure to liver and kidney damage to human body.
LD506, 517 mg/kg (through the mouth) of rats, LD5015, 200 mg/kg (rabbit skin test).
Packing and storage:
200 kg/barrel.In the process of industrial and commercial storage and transportation and use, can take general protection.No special requirements.This product is a non-dangerous goods, should be stored in a cool, dry place.Shelf life of 36 months or more.
Film-forming agent ester alcohol 12 method of use:
1, in the general case, twelve ester alcohol content in latex solid content of 3-9%.Large join quantity can get better effect.When more than 12%, will cause certain influence to the stability of the emulsion
2, in latex paint production, twelve ester alcohol content mainly depends on the hardness of the emulsion polymer, a hard emulsion (high Tg values) to compare soft emulsion (low Tg values) needs more content to reach its membrane effect.In principle, can be directly in any stage of production to join.In addition, using the same emulsion of different recipe (PVC), will also require different ester alcohol addition amount.
3, can be divided into two times to join, can give full play to its advantages:
A, add 1/2 amount in grinding phase, twelve ester alcohol will help yan/packing of wetting and dispersing.
B, 1/2 amount in paint mixing phase, twelve ester alcohol will help suppress bubbles. |
