1.The application of wax auxiliary in water-based coating and printing ink
With the development of the coating technology, the production and refined processing of micronized wax powder have been massively improved, specially in the aspects of the stability of quality and variety. There are 2 mainstream methods of technology: the one is high-pressure-air-flow production way, the other is fusion-spraying methodology. The fusion-spraying methodology is suitable for low molecular weight, linear structure and low viscosity wax, since the raw material is with the performance of abrasion resistance and solvent resistance. Longhai chemical have been producing the micronized wax powder by the method of air-flow-smash independently since 2005, and we are the earliest manufacturer which had started to produce micronized wax powder.


The wax auxiliary agent in the water-based coating is mostly providing the performance of hand feeling, abrasion resistance, matting, anti-settling, and sand ripples effect. It gathered in the surface of the coating to achieve different effects as expectation. The wax of low melting-point is available to increase the smoothness of the surface, the wax of higher melting-point (>145) is with anti-skinning effect, which means to decreasing the smoothness of the surface.
Based on different usage, Longhai chemical have developed a serial of products, which are mainly used in solvent system of industrial coating. The micronized wax powder for increasing anti-scratch hand feeling is 202, 208, 239, 256, 256A (202 is the best cost-efficiency product in ink printing, and you can choose 205 if low price is demanded). 239 is with good gloss retention, PTFE wax 236 is with excellent RCA resistance and scratch resistance. The micronized wax powder 236 was developed in 2003, which was used in water-based varnish, with no delamination or crusting.

The usage of 207 wax powder in UV printing ink of ice-point snowflake 
UV snowflake printing ink is fine pattern, smooth hand feeling, as long as uniform, smooth and fine wrinkles at the surface of the printing matters, with elegant permutation, which are extensively applied in the high-class package materials of cigerate, wine, tea and etc. The 207 wax powder can effectively increase the smoothness and covering effect in ice-point printing ink.


2. Sand surface wax powder
Longhai chemical have been manufacturing the micronized wax powder and sand surface wax powder, and we are the first maker who produced sand texture wax of various hand feeling by taking use of wax in different particles size. The quality of our products are close to the similar types of US brands, and we have accumulated rich technology experiences in the stability performance of the products, we exploited the sand-surface wax powder by the particles sizes from 10mm to 200mm, in order to satisfy the demands of our clients. These products are extensively applied in the high-class package materials of cigerate, wine, tea, plastic film and etc.

3. Water-based micronized wax and wax emulsion
In consequence of the specific gravity and polarity, the micronized wax powder are not able to exist stably in the system of aqueous vanish, our 256 water-based micronized wax powder can effectively enhance the abrasion resistance and hand feeling without layering swiftly.
