KY-204 · Convenient application
A single-component hand-applied grade designed for convenient use. Confirm substrate compatibility, application tools and primer selection before work begins.
SINGLE-COMPONENT POLYUREA
Single-component polyurea for detailed protection.
KY-204 / KY-205
From selection to hand application.
Kangyuan single-component polyurea is designed for hand application and detail protection. Compared with two-component materials mixed on site, it reduces weighing and proportioning steps, supporting work on joints, vertical surfaces and repair areas.
Performance depends on the grade, surface preparation, coating thickness and curing conditions. Consider the substrate, sunlight, exposure media and application conditions when specifying the primer, functional coating and topcoat.

KY-205 · Yellowing resistance
A single-component grade with resistance to yellowing. Consider this option where colour and appearance retention matter. Confirm outdoor service conditions and the topcoat system with the manufacturer.
Flexible detailing & repairs
Assess hand application for corners, pipe penetrations, terminations and local repairs. Before repairing an existing coating, verify compatibility and intercoat adhesion.
Where might a single-component system fit?
Potential applications include roofs and facades, pipe-joint coating, complex details, local repairs and foam sculpture protection, subject to substrate and service assessment. Prolonged immersion, chemical exposure and heavy wear require specific confirmation of grade suitability and supporting evidence.
Single-component still needs application control
Check substrate strength, cleanliness, moisture and environmental conditions. Follow the supplied grade's instructions for usable life after opening, thinning, coat thickness, recoating and curing. Do not substitute hot-spray curing times or test values.

APPLICATION GUIDE
Five stages of single-component application.
01 / Define service conditions
Specify the substrate, area, indoor or outdoor exposure, colour and service requirements to select the grade and system.
02 / Prepare the surface
Remove laitance, dust, oil and loose material, and repair defects. Derust metal in accordance with the coating system.
03 / Trial and prime
Check compatibility and adhesion in a representative trial area. Select a suitable primer and treat pores and details.
04 / Apply controlled coats
Follow the instructions for tools, coat thickness and recoating intervals. Check corners, overlaps and terminations.
05 / Cure and inspect
Allow the specified curing period and inspect appearance, thickness and required properties before putting the coating into service.
