Our company mainly has Polyamide Resin Co-solvent, Polyamide Resin Alcohol Soluble and so on. Polyamide Resin Co-solvent Common co-soluble polyamide resin is a kind of economical and practical resin, which is developed accommodating to the market requirement. It has good stability, good solvent release,marvelous glossiness, strong adhesive power, fine gel resistance. In indoor temperature, it can turn-fost, widely be used to printing fields. Polyamide Resin Alcohol Soluble The alcohol-soluble Polyamide resin, is easily dissolved in alcohol. It can be dissolved in 95% dehydrated alcohol, dissolves aids the release is extremely good .It widely used in the domain such as gravure printing ink of plastic film, the flexo printing ink of plastic film domain. Features: •Excellent solvent release •Excellent gloss •Excellent gel resistance •Excellent pigment wetting •Excellent water resistance •Excellent blocking resistance •Good grease & chemical resistance •Low odour and color Application: Gravure printing ink. Flexo printing ink. Over-printing varnish

In today's packaging and other printed materials, in addition to the use of bronzing process, offset printing gold printing process is still used by many manufacturers. Ink has the advantages of fine and solid imprint, good metal texture, strong hiding power, high floating force, strong metallic luster and low cost. Offset printing enterprises can directly choose gold color offset ink products or use copper gold powder and offset gold oil to self-adjust salty gold ink printing. First, the basic composition of offset gold ink: Bronze powder 30～50% Gold color Offset printing  oil 70～50% mix the bronze powder with gold Oil homogeneously can become gold ink. Second, the cause of the discoloration of the printing gold and preventive measures: 1. Fountain solution pH value and ink balance. In offset printing based on the principle of hydrophobic part of printing plate and hydrophilic principle of non graphic part, the acid substance in the fountain solution can cleaning and remove the dirt. However, if the acid is too strong, the gold printing  will be changed color and lose its metallic luster, resulting in printing plate pattern, slow drying of imprint and sticking on the back. If the acidity is too weak, the picture and text on the printing plate will be dirty and paste. Therefore, the general fountain solution pH value control in 5 ~ 6 is appropriate. Water ink balance is to use as little water as possible on the premise that the printing plate is not dirty and paste, so that the emulsification of the ink is controlled within the minimum range of 25%. Because the water is too much, it is easy to cause the printing gold ink color is too light, the gold ink is dull, the color is not bright, the gold ink is emulsified, the paper stretch deformation causes the overprint inaccuracy and other quality defects; too little of water, easy to make the page dirty, greasy and the emergence of parallel paste, so it is very important to master the balance of ink and water. In addition, the intermediate roller must be separated from the ink path and waterway system, which is also an essential method to avoid. 2. Printing speed. If the printing speed is too fast, it is easy to produce intense rubbing between the rollers, and then the heat generated will change the color of the ink. The general experience is that it should be controlled at 5000 sheets per hour. 3. Oxidation of bronze powder. Bronze powder has the disadvantage of easy oxidation and discoloration, so the bronze powder must be kept in closed air as far as possible, and the storage time should not be too long. 4. PH value of gold blending oil. Bronze powder is easy to oxidize, so the gold adjusting oil used must be fast drying and fast solidifying resin oil with low oxidation property and neutral pH value. In order to avoid oxidation due to long-term storage, it is better to use the self-adjusti...

Aldehyde resin is a kind of aldehyde condensation resin, which is colorless or yellowish. It is soluble in almost paint solvents but not in water and compatible with practically all coating raw materials, it is excellently yellowing-resistant. Usage: 1. Mainly used in solvent-based ink, paint, general color paste, adhesives and other systems, used to improve the gloss, adhesion, fast drying, leveling, fullness, wettability, hardness, toughness, solid content and other properties of the product. 2. Used in nitrolacquer, the solid content, gloss, fullness and adhesion of the system can be improved. It is suggested to use about 5% in the whole system. 3. It can be used for mechanical finish, primer and repair paint, hammer finish, automobile varnish, automobile repair paint, motorcycle paint, bicycle paint, etc. It can improve the coatings'fullness, hardness and impact resistance. It is suggested to use about 5% in the whole system. 4. Used in paper coatings of nitrocellulose or acetyl cellulose. It can improve its fast drying, whitening and luster, and has excellent flexibility. At the same time, it can improve its wear resistance and brush resistance, and can obtain high elastic surface. It is suggested to use about 5% in the whole system. 5. The main characteristics of formaldehyde resin are high adhesion and low softening point. It is very suitable for special coatings such as metal paints and plastic paints which require high adhesion. It is recommended that 5% - 15% be used in the whole system. 6. Used in general high temperature resistant metal paint, baking paint and other high temperature resistant paint systems, it does not produce odor or bleaching resin, can accelerate the initial physical drying process, used to improve the dryness of paint. It is suggested to use about 5% in the whole system. 7. Used in alkyd resin paint to improve gloss, adhesion and weatherability. It is recommended to use 3%-8% in the whole system. 8. Used in chlorinated rubber paint and vinyl chloride copolymer paint, it can reduce viscosity, improve adhesion, reduce film holes, increase gloss, etc. It is recommended to replace 3% - 10% of base material.
