GUUDPOLY® RDP, Water Repellent, Gypsum Retarder for Joint Mortar from Goodyear Chemtech

Joint Mortar

Joint filling mortar is divided into two categories: cement-based and gypsum-based joint filling mortar. It is mainly used for filling gaps between various concrete boards, tiles, gypsum boards, and partition wall panels. Joint filling mortar is required to feature high strength, reliable waterproof performance, good flexibility, and non-shrinkage properties.

Joint Mortar

GUUDPOLY^® Redispersible polymer powder improves the adhesion strength, compressive strength, flexural strength, and waterproof performance of joint filling mortar.

GUUDPOLY^® Water Repellent can effectively enhance the stain resistance and waterproof performance of mortar surfaces, and reduce water absorption.

GUUDPOLY^® Gypsum Retarder can effectively control the setting time of gypsum-based mortar without affecting the final strength of the mortar.

Cement-based Joint filler

Cement-based joint filler is a rigid, cementitious powder joint compound formulated from cement, mineral aggregates, and functional admixtures. After mixing with water and curing, it develops high compressive strength, good dimensional stability, and excellent bonding strength. It is characterized by low shrinkage, high hardness, and strong impact and moisture resistance, making it suitable for heavy-load and damp interior partition projects.

Cement-based joint filler is mainly used for joint treatment of polystyrene particle partition boards, cement foamed partition boards, and precast concrete components.

Gypsum base Joint Filler

Gypsum-based Joint Filler is mainly used for joint filling and bonding of various gypsum boards. It is a lightweight gypsum joint compound taking building gypsum as the main raw material, mixed with retarders and adhesive additives. It sets quickly with slight volume expansion during curing, effectively avoiding hollowing and cracking at boaRDjoints. It has outstanding workability, smooth polishing performance and good compatibility with all types of gypsum boards, designed for drywall interior decoration with dry, stable indoor environments.
