Product introduction

HEC is a series of non-ionic soluble cellulose ethers, which can be dissolved in hot and cold water, and has the characteristics of thickening, suspending, adhesive, emulsion, film coating and super absorbent polymers protective colloid, which is widely used in paints, cosmetics, oil drilling and other industries.

Paint Application Guide

High thickening effect

● HEC provides excellent coating performance for the latex coating, especially the high PVC coating. There is no flocculation when the paint is thick paste.

●HEC has a higher effect of thickening, can reduce the dosage to improve the economic effectiveness of formulation, while improving the washability of the coating.

Excellent rheological properties

● In the stationary state, the product is completely dissolved, the best coating system to maintain shape and cans thickening state.
● In the tilting state, the system will maintain moderate viscosity, make the product equipped with excellent liquidity, and will not splash.
● During the brushing and roller coating, the product is easy to spread on the base  material, which will facilitate the construction. At the same time, have a good performance on anti-splash.
● Finally, when the paint coating is completed, the system viscosity can immediately resume, and the coating will be sagging at once.

Dispersion and solubility

● HEC is dissolved after a delay in processing, in the case of dry powder added, can effectively prevent caking. Ensure that HEC powder begin to hydration after fully dispersed.
● After proper surface treatment, HEC can adjust the dissolution rate and viscosity increasing speed well.

Storage stability

● HEC has good bio-stability, provide sufficient time for the paint store. Effectively prevent and pigments and filler sedimentation.

User's answer more types of additives. Commonly used hardeners, retarders, matting agents and softeners. The additive used to accelerate the hardening and increase the gloss is called the hardener; the slow drying is called the retarder; the matte weaker is called the matting agent; the elasticity for the paint layer is called the softener.
Q:What are the benefits of car additives to cars?
For your question, it is understood that the gas station sold in the gasoline additives are clean detergent, the car fuel intake system, especially the nozzle, intake valve in the sediment cleaning effect, not on Engine has an adverse effect. But can not clean the throttle. In the process of car driving can be the fuel intake system of sediment gradually clean, significantly improve the fuel atomization effect, so that combustion more fully, the thermal efficiency, so as to achieve a certain fuel efficiency. Regular use can effectively remove the car fuel system deposits, keep the fuel intake system and spark plug cleaning, thereby reducing fuel system maintenance costs and extend vehicle life. At present the regular gas station sales of gasoline, have been in accordance with the provisions of the proportion of the addition of full detergent. Fuel oil is equivalent to fuel cleaners, and has been added to the steam, diesel detergent similar, therefore, usually join the ordinary model effect is not obvious, if the vehicle in the urban areas for a long time, then add some still good, hope My answer will help you.
Q:Tofu for what additives

Q:oil/fuel additives?
Just from what I've heard from people I work with, I would not consider any oil additives. You keep oil in your car 3500 to 5000 miles, you don't change it as much as gas, and it plays a very important role in the durability of your engine. Personally, I wouldn't mess with the oil. Lucas Fuel Injector/Carburetor Cleaner works pretty good though as a gas additive.
