Product Details

Product Overview

Hebei InnoNew Material Technology Co., Ltd. supplies high-performance gypsum retarder, a special chemical additive designed to adjust the setting time of calcined gypsum, plaster of paris, gypsum mortar, gypsum board, self-leveling gypsum flooring and gypsum casting products.

This product effectively delays the hydration reaction of gypsum hemihydrate, significantly prolongs available working time, avoids premature coagulation during construction and large-area pouring, eliminates material waste and construction failure, while hardly damaging the final mechanical strength and bonding performance of cured gypsum products.

Core Product Advantages

Stable Retarding Effect & Wide Adjustment Range

Flexible setting time adjustment according to dosage addition; excellent stability under different water-gypsum ratios and ambient temperatures, no sudden acceleration or delayed excessive hardening.
Minimal Strength Loss

Low negative impact on final flexural strength and compressive strength of hardened gypsum; no surface blooming, discoloration or efflorescence on finished gypsum panels.
Excellent Compatibility

Perfectly matched with gypsum water reducer, thickener, anti-cracking fiber and other conventional gypsum additives; no mutual repulsion or performance degradation in compound formulas.
Easy to Use & Wide Applicability

Powder form with good dispersion, easy to mix evenly in dry gypsum powder; applicable to industrial gypsum board production, construction plaster, decorative gypsum lines, gypsum grout and self-leveling floor engineering.

Typical Application Scenarios

Gypsum wallboard / drywall continuous production lines
Construction plaster, hand-applied gypsum base coat & finish coat
Decorative gypsum moldings, art casting gypsum crafts
Gypsum self-leveling underfloor screed
Tunnel grouting, gypsum joint filler and dry mixed gypsum mortar
