Coil Coating Silica Dioxide Powder Anti Corrosive Pigments

Silica Anti Corrosive Pigment For Protective Coatings Solvent and Water Based Epoxy Primers

Components: Silica Dioxide pigment through surface treatment.

Main features:

Pigment AC-80 and Pigment AC-85 are both very efficient corrosion inhibitors in solvent based epoxy primers, while Pigment AC-75 may be used in high performance water based epoxy primers.

Generally, the replacement loading for Pigment AC-80 20 to 60% by weight of zinc phosphate or modified zinc phosphates. Pigment AC-85 should be used at 20 to 40% of the original loading.

In new formulations the recommended loading for good performance in general purpose epoxy primers is 6-7% by weight on the total formulation for Pigment AC-75 and 2.5-3.5% by weight on the total formulation for Pigment AC-75. (assuming a formulation with 50-60% Non Volatiles by Volume).

It should be noted that in epoxy primers it is possible to incorporate Pigment AC-80 and 85 both in the Hardener (part B) and in the epoxy base (part A).

Pigment AC-80 and AC-85 may also be used in both solvent based and water based epoxy primers as cost effective and high performance replacements for standard zinc phosphate on a 1:1 basis.

Widely applicable:

Common coil coating primer formulations are based on polyester resins heat cured with amino resins with acid catalysts. This is due to the very high throughput speed of coil coating lines where typical residence time at the PMT (Peak Metal Temperature) is 20-35 seconds.

The alkaline nature of SKYSIL grades may occasionally cause formulation instability and slow cure with the acidic catalysts. The use of blocked catalysts are therefore recommended, together with minor formulation modifications. The use of acidic ingredients such as certain organic corrosion inhibitors should be avoided.

Choice of the blocked catalyst is of critical importance for the successful performance of the formulation. They should be tested for performance, paint stability and cure retention after accelerated aging. For blocked Isocyanate systems containing Pigmentan, the use of tin based catalysts is not recommended.

Introduction

Our reputation as a key national supplier is built upon the foundation of quality and integrity. The company has independently researched, developed and manufactured several series products including Silica Matting Agent, Matt Hardener, Fumed Silica, Zinc Stearate and Alumina.

Our product development is guided by accurate market analysis. We have successively established R&D Centers of Matting Agent, Fumed Silica, Zinc Stearate, Matt Hardener, and Alumina.Application Research centers were also created for mediums such as paints, ink, textiles, leathers and new energy materials. These Modern facilities form the very core of our development system and are staffed by a professional taskforce of technical personnel. Their contributions have yielded environmental-friendly products such as the low oil absorption UV matting agent, a compound that was specifically designed to minimize the VOC emission of paints. These Products are the building blocks of eco-friendly alternative engry solutions. Their ability to protect leather and prevent the corrosion of metals make them idea for floor coating, glass paint, and the making of woodenware.

Quanxu Technology firmly believes that technological advancement is the precursor for market performance. We have established major distribution centers in one overseas location and 3 domestic regions.

Product quality has always been at the very top of our priorities. Over the years, we have imported a number of advanced testing instuments enhanced quality control and inspection. Quanxu operates in strict adherence with all relevant safely standards. Our export products are approved by international recognized standards such as SGS and ROHS.

More than a decade of groundwork has allowed us to penetrate overseas markets in regions including Europe, the Middle East, South America, Southease Asia, Africa, Etc. We have established a long-term cooperative partnerships with international chemical mega-corporations such as Valspar and AKZONOBEL.

Through sustained growth and expansion, Quanxu Technology strives to become a world-leading supplier of chemical materials. With quality and integrity, we will create an enterprise that can withstand the test of time!!
