H305 　Polyurethane Low-shear thickener

◆ Product Introduction

H305 Product Yes Manufactured using advanced foreign production processes and equipment, as well as high-quality imported chemical raw materials. of the ， Used for Provide Suitable Low , middle Shear Viscosity and Pseudoplastic Rheological Properties A non-ionic, hydrophobically modified ethoxylated polyurethane (HEUR) rheology modifier.

H305 Offering excellent low-shear viscosity and Anti-sagging performance At the same time ， It strikes a balance between medium- and high-shear viscosity, enhances water resistance, and can simultaneously... Imparts good thixotropy to the coating, paintbrush. and Roller's paint-impregnation capacity ， Good internal tank structure and excellent flow. With Dripping of the Balance. Its Shear-thinning of the Rheological properties are also suitable for systems such as emulsions, dispersions, water-based clear coatings, and high-gloss tinted paints that are appropriate for spray application.

H305 Widely used in water-based industrial coatings, architectural coatings, tinted paints, clear coats, and coating systems with gloss and high gloss. H 305 It exhibits excellent water-phase diffusion properties and can be used alone in coating formulations or combined with polyurethane rheology modifiers such as H003, which enhance high-shear viscosity and leveling performance, thereby achieving an ideal balance of viscosity across different shear rates.

Compared to similar products in the domestic and international markets, the H305... The product has higher Cost-effectiveness—its product performance and usage results fully meet or even exceed those of comparable imported products.

◆ Product Features

Main performance characteristics of H305 product when used in water-based paints:

◆ Physical and chemical properties of the product

The following are typical data and should not be considered specifications.

◆ Instructions for Use

This product This product is suitable for adding directly at any stage of production in most systems without the need to adjust the pH. For ease of use, it is recommended to add it slowly in the later stages and allow sufficient stirring time to ensure thorough mixing. If necessary, it can also be pre-diluted with water (1:1) using co-solvents such as ethylene glycol or propylene glycol before being added slowly with adequate stirring.

The usage of this product is determined based on the customer’s formulation design. The recommended addition level is 0.2% to 1.0% of the total formulation weight. Customers can also combine this product with other types of thickeners according to different requirements for production, storage, application, and film formation, in order to meet the rheological performance specifications of the formulation design—for example, to achieve high shear viscosity. JA004、 Provide middle Shear viscosity of the JA104 、Provide thixotropic H 306 Wait to achieve an ideal balance of viscosity under different shear rates.

◆ Packaging and Storage

Packaging: Available in 25-kg and 200-kg plastic drums; other packaging formats can be provided upon customer request.

Storage: The product should be stored in a tightly sealed container in a cool, dry, and well-ventilated warehouse. During winter storage and transportation, appropriate antifreeze measures should be taken (if frozen, after thawing, stir thoroughly; if no granular crystals are observed upon inspection, the product can continue to be used).

Validity period: two years.
