Alkali-Resistant Transparent Primer


Product Introduction

Water-based transparent primer with good permeability, excellent water and alkali resistance, and outstanding sealing ability. It effectively prevents alkali return and discoloration of the topcoat.

Product Features

Transparent primer with good permeability and outstanding sealing performance

Good alkali resistance and resistance to salt alkali precipitation; Prevent the topcoat from returning to alkali and causing discoloration

Good water resistance, low permeability, preventing rainwater from seeping into the base layer

Good adhesion, high bonding strength, and less likely to bulge or peel off

Green and environmentally friendly, easier construction, can be diluted with water for viscosity

Precautions

Substrate Requirements: The substrate should be firm, flat, clean, and free from floating dust, blisters, cracks, or water seepage. The moisture content should be <10%, and the pH value should be <10.

Climate Requirements: Avoid application in harsh weather conditions such as frost, freezing, rain, or snow. The substrate temperature should be between 5-35℃, and air humidity should be <85%.

Usage Ratio: The alkali-resistant transparent primer can be used directly after stirring evenly. If viscosity adjustment is needed, it should be diluted by a professional according to a fixed ratio, with the water added not exceeding 20% of the total paint volume.

Application Instructions: It can be applied using a spray gun. It is recommended to use a wool roller for rolling, with corners and gaps painted with a wool brush for better coverage.

Tool Cleaning: During construction breaks, rollers, brushes, spray guns, mixers, and other tools should be cleaned with water and dried before reuse.

Storage Instructions: Water-based paints are non-hazardous for transportation. Store in a cool, ventilated place, with temperatures between 5-35℃. The stacking height should be limited to two layers, and the sealed storage period is 1 year.
