Requirements of Highly Durable Sealant
• Good MAF – Lesser joint width Sealing compound should perform• Resistance to Fuels, Hot exhaust & UV.• Good Adhesion & Cohesion.• Resistance to Water & Fuels – When it submerged.• 100 % Leak Proof• Abrasion Resistance.• Durable.• Economical Life Cycle.• Proven Track Records.
Techseal EH – HPP – PQC Sealants
28
TECHSEAL EH-HPP Polysulphide Sealant
Confirms to :
• BS 5212 Part II – 1990 – Fuel Resistance.• BS 4254 – Sunlight Exposure Test.• EN 14187-5 – 2003 – Hydrolysis Tests• PPM 400 – Hardness & Peel Strength• ASTM C – 920 – Staining Test.• IS 12118 - Indian Standard similar to BS 4254
29
Techseal EH-HPP
• Polysulphide Based Sealant• Especially Developed for High Performance.• Movement accommodation capacity 60%• Good elasticity (elongation 650%)and recovery(>85%)• Better fuel & flame resistance.• Better UV and Water resistance.• Performs well in the temp range of -40 to 80 deg.centigrade.• Resistance to UV, Ozone, Alkalies, Lubricant Oils and Fuel.• Life expectancy over 10 – 15 Yrs.• Suitable for Automatic Meter Mixing Equipments. • Most Economical than any other sealant.
30
Current Scenario of PQC Sealant in India
In the past all Indian codes specified sealing compound as per BS 4254
Now IRC, NHAI, All Airports started using sealing compound as per the BS 5212 part II, 1990 since last 2 years.
Few points which are considered to be very important for the durability point of view & are missing in BS 5212 specification, but the same are available in BS 4254, PPM 400, EN 141875 & ASTM C 920.
Additional Tests required are :
• Elasticity• Peel Strength• Hardness• UV Resistance.• Staining Test• Tensile Strength• Hydrolysis Test.
31
Techseal PU-2 / Techseal PU-1 Polyurethene Compound
• Polyurethane Based Sealant• Movement accommodation capacity +/- 25% • Good elasticity • Fuel resistance.• UV and Water resistance.• Performs well in the temp range of -40 to 80 ° Centigrade.• Resistance to UV, Ozone, Alkalies, Lubricant Oils and Fuel.• In case of Single Component – No Need of Mixing – Ease of
application.• Life expectancy over 8 -10 Years.
Standard Compliance :• BS 5212 (1990) & BS 4254
32
Conclusion:
• Random Testing of Sealant at Independent Lab should be made compulsory. ( All Specifications)
• Use of Automatic / Semi Automatic Mixing Equipments should be used to avoid Human Error for 2 K Sealants.
• WE ASSURE YOU THE BEST QUALITY PRODUCT AVAILABLE FROM INDIAN MNC WITH OUR TRAINED APPLICATORS.
• TILL DATE MORE THAN 1.5 CRORE RMT SUPPLIED IS THE TESTIMONY TO OUR COMMITMENTS TO THE NATION.
• NO COMPANY IN THE FIELD PROVIDE 10 YEARS WARRENTY TO THE PRODUCT AT LESSER RATES.
