The wind blows a little bit colder, and the clouds are moving on with every autumn breeze! it’s the season for Junjiang’s new product launch! I remember Junjiang brought you 6 exciting products this spring, and the response was very good! Through half a year’s unremitting efforts, Junjiang people have developed another 6 sets of new products at “New Forms·New Products” Autumn New Product Launch! Come and have a look!
New conductive material for high whiteness and transparent system: BC-B50
Conductive powder BC-B50 is a new conductive filler developed by Junjiang company this year for the requirements of conductive performance: powder particle size, powder color and hiding power of conductive filler in the high-end anti-static field.
The basic material of BC-B50 is mainly acicular titanium dioxide, and the conductive material is n-type semiconductor material tin antimony oxide (ATO). Liquid phase coprecipitation combined with high temperature calcination was used to prepare. It has finer particle size, whiter color, larger conductive specific surface area, stronger stability of powder resistivity, and pH value of 10% aqueous solution is 5 ~ 7. Through third-party testing, no harmful substances such as lead, mercury and cadmium were detected in combination with EU ROHS standards. Its annual production capacity is more than 200 tons.
Optimization scheme of high cost performance quick drying epoxy curing agent
D6509 is an excellent phenolic amide epoxy curing agent. The ratio of 901-75 resin to liquid epoxy resin (EEW = 190) at room temperature is 100:30. It has good flexibility and curing speed, and is not easy to blister in salt spray test. It is widely used in the anti-corrosion field of low-cost steel structures.
Its appearance is reddish brown and yellow transparent liquid, the viscosity is 5000-15000 (CPS / 25 ℃), and the operation time is 20-30min (pure solid content); 120 min (diluted to 50%), amine value 250 ± 30 (mg KOH / g), active hydrogen equivalent 200.
D650a is an excellent polyamide epoxy curing agent. It can improve toughness, adhesion, curing speed, weather resistance, chemical resistance and salt spray. It is widely used in the fields of plant steel structure, ship anti-corrosion, bridge steel structure anti-corrosion and so on.
The appearance is amber liquid, the viscosity is 5000-40000 (CPS / 40 ℃), the recommended dosage of 100g e20-75 resin is 30g, and the active hydrogen equivalent is 190 ± 10.
How to prevent corrosion under the trend of environmental protection
Anti rust pigment bc-y90 is a new generation of environment-friendly white developed by Junjiang. It is an ideal functional anti-corrosion (rust) pigment filler for traditional toxic anti rust materials such as lead and chromium. The performance of inorganic materials is permanently stable, non catalytic, and has no effect on the color, gloss and leveling of paint film; The content of phosphate is higher than that of traditional products on the market; Form a passivation layer with the surface of metal materials, chelate with each other, and improve the adhesion; The product has good particle size control, stable storage and easy dispersion.
The appearance is pure white powder, the pH value of water suspended solids is 5.5-6.8800 mesh, the sieve residue is less than 1%, the oil absorption is 25-35g / 100g, and the addition method is internal extrusion 10-15%.
Promotion of waterborne additives
Addhelper & vatix are two major auxiliary brands of Junjiang technology. Addhelper focuses on general purpose and economic type. Vatix’s main products: high performance and high cost performance.
The recommended defoamer series, a809, has strong defoaming and foam inhibition, strong versatility and high economy; V810w has excellent compatibility, long-lasting and stable defoaming, strong transparency and high color development; V820w strong defoaming, extremely suitable for thick slurry system.
The recommended wetting dispersant series, v990, has strong universality, takes all inorganic and organic pigments, and can prepare all kinds of paints; V992 has remarkable anti sinking characteristics and is suitable for high demand coatings, inks / 3C, etc; A902 is economical and applicable, with strong viscosity reduction. It is especially suitable for inorganic pigments.
The recommended base material wetting agent series is a542 waterborne epoxy surface coating, which can reduce surface tension, strong adaptive wettability, auxiliary defoaming and dispersion.
Alternative selection of traditional chromium antirust materials under the new national standard
Zinc strontium phosphate jp-b808 is light yellow powder in appearance, with oil absorption of 25-40g / 100g. The recommended addition amount is 0.5-2%. Both oil-based system and water-based system can be used, especially for water-based epoxy (epoxy ester), water-based acrylic acid and water-based alkyd to improve resistance (salt spray resistance, salt water resistance and anti flash rust); 1: 1. Replace traditional chromium materials such as strontium chrome yellow with the same dosage; Environmental protection requirements can be limited by 30981-2020 industrial coatings harmful substances and heavy metals (dosage ≤ 2%).
So far, Junjiang's autumn new product launch in 2021 has been successfully completed. Thank you for your patience last night, the wonderful speeches of all speakers and the hard work of the staff behind the scenes. "New forms and new products" Junjiang will continue to strive to develop better products and provide more thoughtful services for customers. Thank you again for your trust and support! See you next year!
