Our Products

Three Cryogenic Materials, One Complete Solution

From load-bearing tank installation to insulation bonding — covering every cryogenic joint in LNG carriers and independent tanks.

JM-98

Cryogenic Epoxy Putty

Load-bearing epoxy putty for Type A / B / C independent LNG tank installation. Poured at the tank saddle, it cures into a structural support that keeps its strength at -196°C.

Compressive strength (-196°C)≥210 N/mm²
Shear strength (-196°C)≥70 N/mm²
Thermal conductivity≤0.6696 W/m·K
Optimal thickness25–40 mm

JM-98L

Liquid Epoxy Resin

Low-viscosity liquid epoxy for Type A / B independent tank installation. Flows by gravity or pump pressure into the pouring zone for void-free load transfer.

Compressive strength (-196°C)≥300 N/mm²
Shear strength (-196°C)≥85 N/mm²
Linear shrinkage≤0.001
Pouring methodGravity / pump

JM-2601

Ultra-Low Temperature Adhesive

Two-component, solvent-free, flame-retardant polyurethane adhesive for bonding foam insulation to foam, and foam to metal in liquefied gas carriers. Cures at room temperature.

Service temperature-196°C ~ 150°C
Oxygen index≥28%
Mix ratio (A:B, weight)9 : 1
Pot life (23°C)≤80 min

Applications

Where Our Materials Work

Every cryogenic joint in the LNG value chain — from shipyard saddle to insulation panel.

🚢

LNG Carriers

JM-2601 bonds foam insulation panels to each other and to metal structures in liquefied gas carriers — room-temperature cure, no corrosion, no by-products.

🏗️

Independent Tank Saddles

JM-98 putty and JM-98L liquid resin form the load-bearing chocking between Type A/B/C independent tanks and their saddles.

❄️

Cryogenic Piping & Terminals

Low thermal conductivity (≤0.5 W/m·K) and -196°C stability make the JM-98 series suitable for LNG piping supports and terminal tank foundations.

Certifications

FAQ

Common Questions

What is the shelf life of these products?

12 months from the date of production when stored at room temperature in a dry, ventilated warehouse (4°C–38°C). Products past shelf life may still be used after passing inspection.

Do you provide installation guidance?

Yes. We provide detailed application procedures for every product, and on-site pouring and curing guidance can be arranged for project volumes. Contact us to discuss your installation plan.

What is the minimum order quantity?

We support trial orders as well as volume contracts for shipyard projects. Send us your estimated quantity via the inquiry form or WhatsApp for a tailored quotation.

What is the typical lead time?

We keep regular stock of the JM-98 series. Lead times depend on quantity and destination — contact us for the current production schedule and sea-freight options.

Are these products certified for international vessels?

JM-98 epoxy putty holds type approval from 9 major classification societies (BV, CCS, DNV, ABS, KR, LR, NK, RINA, RS) and is accepted for installation on vessels classed by DNV and others worldwide.
