Technical data sheet for Gypsum retarder（GR-A01）

2026-02-03

1. Introduction

GR-A01 is a highly efficient gypsum retarder based on modified amino acids
2. Physical Properties

3. Performance
GR-A01 is mainly applied in gypsum-based products and can endow the products with the following characteristics
• High retarding efficiency and low dosage
• The dosage has a linear relationship with the setting time of gypsum
• It has good adaptability and is suitable for various types of gypsum
• It has a minimal side effect on the strength of gypsum
• Odorless, non-toxic and pollution-free

4. Application
GR-A01 is mainly recommended for application in gypsum-based self-leveling mortar, plastering gypsum, jointing gypsum, gypsum components and gypsum decorative line mortar, etc.. The actual dosage should be determined in advance through experiments.
Storage
In the sealed original packaging , the storage period is 12 months. If it has exceeded the usage period but no lumps, it can still be used. It must be stored in a cool and dry place. To prevent moisture from seeping in, opened packages should be sealed as soon as possible.

Package
25kg bag, Multi-layer paper-plastic composite bag (lined with polyethylene film)

7. Industrial safety and environmental protection
— There is an explosion risk when exposed to static sparks or fire sources
— Exhaust and ventilation devices should be installed at the usage place
— Glasses or chemical eye mask must be worn
