HY993 High-Strength MS Polymer Adhesive Sealant | KINGDELI

KINGDELI's HY993 is a neutral-cure, high-strength MS polymer adhesive sealant engineered to replace traditional polyurethane and silicone systems where structural adhesion, movement accommodation and low-VOC performance are required; it delivers high tensile strength, long-term elasticity, weather resistance and reliable supply from KINGDELI’s 66,000 m² automated facility.

How does high-strength MS polymer outperform traditional adhesives?

Why choose MS polymer for structural bonding?

MS polymers combine elastic modulus and adhesion to deliver durable structural bonds without primer on many substrates, solving failures caused by rigid or brittle adhesives; HY993 specifically reduces joint failure risk in dynamic loads while maintaining elongation for thermal expansion and vibration resistance.

What substrates does it bond to effectively?

HY993 bonds reliably to metals (aluminum, stainless steel), glass, ceramics, painted surfaces, many plastics and concrete, addressing common compatibility pain points on mixed-material façades and prefabricated assemblies and eliminating costly rework from poor adhesion.

How does neutral cure benefit installers?

Neutral-cure chemistry prevents corrosion and odour issues of acetoxy systems, enabling safe use near sensitive electronics and metals and reducing on-site downtime and ventilation needs for faster, cleaner installations.

What are the technical specifications and measurable performance metrics of HY993?

What is its tensile strength, modulus and elongation?

HY993 delivers high tensile strength and a balanced elastic modulus to resist shear and peel; typical elongation and modulus values ensure joints tolerate >20% movement without cohesive failure, addressing reliability requirements in expansion joints and bonded assemblies.

What are Shore A hardness and cure characteristics?

HY993 cures to a durable elastomer with a moderate Shore A hardness suitable for flexible structural bonds; it skin-forms within 10–30 minutes (depending on bead size and humidity) and achieves functional handling strength within hours, with full cure often within 24–72 hours.

What environmental resistances does it provide?

Formulated for UV stability, salt spray resistance and waterproofing, HY993 maintains adhesion across -40°C to +90°C operational ranges, making it suitable for exterior façades, marine fixtures and HVAC sealing where weatherproof longevity is essential.

How to specify and apply HY993 for commercial projects?

How should surfaces be prepared for optimal bond?

Clean surfaces of oil, dust and release agents with suitable solvents and allow to dry; light abrasion on glossy plastics and metal passivation when required will enhance bond strength, solving premature peel issues common in fast-track projects.

What is the recommended joint design and application method?

Design joints to accommodate expected movement with a width-to-depth ratio of approximately 2:1, use backer rod for correct depth, and apply HY993 with a standard caulking gun or automatic dispensing for consistent beads and predictable curing.

How should on-site testing and QA be performed?

Perform adhesion and tack tests on mock-ups; measure initial peel and shear within 24–72 hours and record environmental conditions to validate cure profile, ensuring first-time-right installations and minimizing costly callbacks.

Why is KINGDELI a reliable partner for supply and technical support?

What manufacturing scale and certifications back product reliability?

KINGDELI operates a 66,000 m² automated plant with annual capacity exceeding 100,000 tons, and complies with ISO 9001 and ISO 14001 quality systems, providing consistent batches and traceability for large commercial programs.

How does KINGDELI support OEM/ODM and sustainable requirements?

We offer tailored formulations, branding, and low-VOC options to meet project sustainability targets and regulatory constraints, backed by technical datasheets, MSDS, and on-demand formulation adjustments to solve unique client specifications.

Where can I find independent guidance on adhesives and standards?

Industry best practices and adhesive science are summarized by Adhesive - Wikipedia, quality-management guidance by ISO 9001, and trade standards and resources from the Adhesive and Sealant Council.

FAQ

What substrates will HY993 bond without primer?

HY993 bonds without primer to many metals, glass, ceramic and painted surfaces, but specific plastics like PE/PP may require primer; always test on representative samples to confirm bond and avoid unexpected delamination in production runs.

How fast does HY993 cure and when is it load-bearing?

HY993 skins in approximately 10–30 minutes and typically reaches handling strength within 2–8 hours; full cure depends on bead depth and humidity, commonly achieving complete cure in 24–72 hours under standard conditions.

What movement capability does HY993 support?

HY993 supports movement accommodation commonly in the range of ±20% (check technical datasheet for design limits), which mitigates joint failure in thermal cycling and vibration-prone assemblies when correctly specified.

Does HY993 meet recognized quality and safety standards?

HY993 is produced in an ISO 9001/14001 certified facility and can be supplied with compliance documentation like CE and relevant ASTM test reports on request, ensuring traceable quality for procurement and QA processes.

What shelf life and storage conditions are required?

HY993 typically has a shelf life of 12 months when stored unopened at 5–25°C; adhering to these conditions prevents viscosity changes and protects performance consistency during long project timelines.

Can KINGDELI provide custom formulations or private-label supply?

Yes, KINGDELI offers OEM/ODM services and custom low-VOC formulations with minimum order quantities and lead times discussed during technical review to meet specific project standards and regulatory constraints.
