Buying Guide

Match viscosity to application

High-viscosity formulas like surface-curing silicones offer gap-filling strength for bonding plastics, while low-viscosity sealants are better for thin bead applications and glazing

Check cure type and time

RTV (room-temperature vulcanizing) silicones and surface-curing variants differ in skin-over time and full cure; faster skin-over can speed handling, while full cure affects long-term bonding

Consider color and yellowing resistance

Clear or white sealants suit visible joints; look for no-yellowing claims when clarity over time matters, especially for windows and glazing

Buy by package and value

Multipacks and larger-volume tubes can improve cost per ounce—compare pack sizes and unit counts to match project scope without excess waste
