OGD-71B Polymer-Based Shape-Memory Hot Melt Adhesive

OGD-71B is a light-yellow, transparent, non-toxic hot melt adhesive in block form, specially developed for automotive tire puncture protection and self-sealing applications. Applied to the inner surface of tires using specialized equipment, it forms an elastic adhesive layer designed to help seal punctures, reduce air leakage, and enhance tire safety.

With a melt viscosity of 10,800 cps at 170°C and a Ring and Ball Softening Point of 105°C, OGD-71B provides an initial tack of >20# copper ball and a peel strength of >15 N/in. The recommended operating temperature is 180–210°C, while the adhesive layer is designed to maintain elastic performance within a service temperature range of -25°C to 90°C.

Featuring excellent initial tack, low odor, high bonding strength, and smooth spray application with minimal stringing, OGD-71B offers shape-memory self-healing properties that help the adhesive layer recover and seal punctures. It is suitable for automated inner-tire spray coating lines used in tire puncture protection applications.

Description

Precautions

01. Temperature Control

Avoid prolonged operation above 210°C, as sustained high temperatures may accelerate adhesive degradation and impair its shape-memory self-healing performance.

02.Keep the Melting Tank Covered

Close the tank lid promptly after loading the adhesive blocks to prevent dust and foreign particles from entering and potentially blocking the spray gun.

03.Viscosity Control During Production

Adjust the application temperature to control melt viscosity and meet the requirements of the tire inner-liner spray coating process.

04. Carbon Deposit Removal

If carbon deposits accumulate in the melting tank or heated hoses, clean the affected components first with paraffin or mineral oil, then circulate hot melt adhesive at approximately 135°C through the system to flush out residues. Follow the equipment manufacturer's cleaning procedures.

Key Benefits

01.Shape-Memory Self-Healing for Automatic Puncture Sealing

The specialized organic shape-memory formulation allows the adhesive to rebound and close gaps after penetration by foreign objects, helping seal air-leak paths and improve tire puncture protection and driving safety.

02.Wide Service Temperature Range for Year-Round Performance

Designed to maintain performance within a service temperature range of -25°C to 90°C, the adhesive layer resists hardening and cracking in cold conditions and excessive flow in hot conditions.

03.High Initial Tack for Secure Tire-Liner Adhesion

With an initial tack of >20# copper ball, the adhesive bonds firmly to the inner tire surface, helping reduce the risk of detachment and blistering during long-term use.

04. Smooth Spray Application for Uniform Coating

Stable melt flow and leveling support automated spray application with minimal stringing, helping produce a uniform adhesive layer and consistent self-sealing performance.

05.Low Odor for a More Comfortable Production Environment

The low-odor formulation supports a more comfortable working environment. Its non-toxic formulation in solid form at room temperature makes it suitable for large-scale automated production.

Model

OGD-71B

Specification

Appearance: Light-yellow transparent adhesive blocks
Melt Viscosity: 10,800 cps at 170°C
Softening Point: 105°C (Ring and Ball Method)
Initial Tack: >20# copper ball
Peel Strength: >15 N/in
Safety & Environmental Profile: Non-toxic and environmentally friendly
Operating Temperature: 180–210°C

Material

Shape-Memory Self-Healing Properties: An organic shape-memory hot melt adhesive system with unique recovery properties.
Balanced High- and Low-Temperature Performance: Resists hardening at low temperatures and excessive flow at high temperatures.
Elastic Sealing and Puncture Self-Repair: Forms an elastic sealing layer after melt spraying and cooling. When punctured by a nail, the adhesive can rapidly close the opening, helping maintain an airtight seal.

Storage Condition

Store the adhesive blocks flat in a cool, dry, well-ventilated warehouse away from hot melt equipment and other heat sources to prevent heat-induced softening and sticking. Avoid prolonged compression under heavy loads to prevent deformation. Protect the material from dust and contamination.
Shelf Life: 12 months
