Overview
KL1017-TA is a high-performance epoxy adhesive engineered for demanding industrial applications. Developed as a solution for bonding dissimilar materials, it bridges the gap between structural integrity and environmental resistance. The adhesive is particularly valued in sectors where failure is not an option, such as aerospace and automotive manufacturing. Unlike conventional adhesives, KL1017-TA maintains its bonding strength across a wide temperature range (-40°C to +200°C), making it suitable for components exposed to thermal cycling. Its formulation also resists degradation from oils, fuels, and mild acids, ensuring longevity in harsh operating conditions.
Physical and Chemical Properties
KL1017-TA exhibits a viscosity range of 12,000-15,000 cP at 25°C, allowing for precise application via dispensing equipment. The adhesive typically cures within 24 hours at room temperature, though heat acceleration (80-100°C) can reduce this to 1-2 hours. Shore D hardness post-curing ranges from 85-90, indicating excellent load-bearing capacity. Chemically, the adhesive's cross-linked epoxy matrix provides exceptional resistance to polar solvents and alkaline environments. Testing shows less than 5% weight change after 500 hours in ASTM Oil No. 3, outperforming many industrial adhesives. Its dielectric strength (~18 kV/mm) makes it suitable for electronic applications requiring electrical insulation.
Main Applications
In automotive manufacturing, KL1017-TA bonds composite brake pads to backing plates, withstanding shear stresses exceeding 25 MPa. Aerospace applications include winglet attachments and interior panel bonding, where its flame retardant properties (meeting FAR 25.853) are critical. The electronics industry utilizes it for potting sensitive components, leveraging its low coefficient of thermal expansion (CTE 50-60 ppm/°C). Industrial equipment manufacturers employ the adhesive for assembling gearbox housings and pump components, where vibration damping is essential. Recent adaptations include use in wind turbine blade repairs, demonstrating versatility across sectors. For optimal results, surface preparation with specialized primers (e.g., AP-130) is recommended for challenging substrates like PTFE or polypropylene.
Safety and Storage
KL1017-TA contains bisphenol-A epoxy resins and amine hardeners, requiring handling per OSHA 29 CFR 1910.1200 standards. Always use nitrile gloves (minimum 8 mil thickness) and chemical goggles during application. Spills should be contained with absorbent materials like vermiculite, never washed into drains. Unopened containers have a 12-month shelf life when stored below 25°C. Once opened, use within 3 months to prevent moisture absorption. Never mix old and new batches, as partial curing may affect performance. For disposal, consult local hazardous waste regulations - uncured adhesive is classified as D001 ignitable waste in many jurisdictions.
B2B Procurement Guide
Industrial buyers should specify KL1017-TA by technical datasheet revision (current: TDS-7.2) rather than generic product names. Standard packaging includes 20kg pails or 200kg drums, with custom batch sizes available for OEM contracts. Leading manufacturers typically provide: - Batch-specific FTIR spectra - Rheology test reports - ISO 10993-5 biocompatibility data (for medical applications) Consider minimum order quantities (MOQs) - most suppliers require 100kg for first-time orders, dropping to 50kg for repeat purchases. Some distributors offer just-in-time delivery programs for automotive production lines. Always validate supplier certifications, particularly for defense contracts requiring ITAR compliance.
