Thickener 6000DS, thickener 638, and PEG-150 cover multiple industries such as industrial coatings, inks and adhesives, textile printing and dyeing, daily chemical washing, and personal care. The core processes involve thickening, rheology modification, suspension stabilization, and emulsification lubrication in water-based systems.

Detailed Description

The PEG-150 distearate series (including thickener 6000DS powder type and thickener 638 liquid type) is a non-ionic high-efficiency thickener that plays a key role in various water-based systems due to its excellent acid, alkali, and hard water resistance, as well as wide compatibility. Data comes from the technical documentation of Hai'an Guoli Chemical Co., Ltd.

Thickener 6000DS (white to off-white powder) is designed for water-based systems, emphasizing high thickening efficiency and excellent flow and leveling properties; thickener 638 (slightly yellow transparent liquid) is a general-purpose rheology modifier, focusing more on imparting moderate thixotropy and a balance of medium to low shear viscosity; PEG-150, with its non-ionic characteristics, serves both thickening and stabilizing functions in surfactant-containing formulations.

Overview of Application Industries and Processes

Product Grade	Application Industry	Specific Process/Scenario	Core Function
Thickener 6000DS	Water-based architectural coatings	Latex paint production	Thickening, anti-settling, anti-spattering, improving roller and brush feel, forming uniform thick film
	Water-based adhesives	Adhesive solution preparation	Precise viscosity adjustment, enhancing initial tack and storage stability, preventing filler sedimentation and stratification
	Water-based inks	High-speed printing	Optimizing thixotropy and rheological curves, ensuring sharp dots, vibrant colors, and reduced misting
	Textile printing	Printing paste preparation	Enhancing water retention and plastic viscosity, achieving sharp print contours, bright colors, and reduced bleeding
Thickener 638	Latex paints	Finished paint formulation	Balancing medium and low shear viscosity, enhancing in-can appearance and film leveling, reducing spattering and sagging
	Water-based industrial coatings	Metal/plastic substrate coating	Adjusting application viscosity, improving anti-settling and hiding power, maintaining stable gloss
	Water-based adhesives	Adhesive consistency control	Controlling adhesive consistency, extending open time, improving wet tack without affecting final bond strength
	Water-based inks	Printability adjustment	Providing required rheology for printability, ensuring transfer rate, no clogging, fine and clear print marks
PEG-150	Personal care and cosmetics	Shampoos, body washes, creams, lotions	Imparting thickness and suspension ability, improving foam texture, smooth cream application, and silky feel
	Household and industrial cleaning	Detergent formulations	Adjusting washing liquid viscosity, improving clingability, stabilizing fragrance and auxiliary components
	Textile lubrication	Spinning/weaving processes	Acting as consistency regulator and protective colloid, reducing friction, preventing fiber damage
	Industrial mold release	Mold release agent systems	Increasing film-forming property and adhesion viscosity, ensuring uniform coverage on mold surface for efficient and damage-free demolding

Application Recommendations

Powder type (6000DS): Suitable for formulations requiring precise metering and long-term storage. It is recommended to slowly add to water under stirring conditions for dispersion and dissolution to avoid agglomeration.
Liquid type (638): Easy to disperse, supports cold blending processes, especially suitable for low-temperature production environments. Can be added directly in the later stages of formulation to adjust viscosity.
PEG-150: Performs excellently in daily chemical formulations containing surfactants. It is recommended to add together with the main surfactant, utilizing the system's self-heating or moderate heating to promote uniform thickening.
Dosage reference: Typically added at 0.5% to 3.0% of the total formulation weight. The specific dosage should be determined through experiments based on the target viscosity.

Precautions

It is recommended to wear dust masks, chemical safety goggles, and protective gloves during operation to avoid direct contact with eyes and skin.
Storage temperature should not exceed 45°C, and relative humidity should be below 70% to prevent moisture absorption and caking.
When handling thickener 6000DS powder, control dust generation carefully. Accumulated fine dust mixed with air may form combustible dust clouds; keep away from open flames.
Under recommended storage conditions, the unopened product has a shelf life of two years.
