Never apply to surface temperatures above 121 C (250 F) or expose to temperatures above 190 C (375 F). Never use in conjunction with fibrous type insulating materials. Exposure to fibrous materials at elevated temperatures can cause auto ignition.
| Notes | Not an insulating material. Uncured material will corrode metals when in continuous contact with water. Insoluble in water and many solvents when cured. Difficult to remove when cured. Limited shelf life can be extended much longer in a freezer. Does not require out-of-service cure time. See
SES N01-F10 for metal substrate protection required. |
Not an insulating material. This cement is nonhardening and does not
require any curing or drying. This cement is recommended where good contact should be maintained between 2 surfaces that are subject to expansion and contraction cycles. Requires no surface preparation. Can be applied to rusty and corroded surfaces. The strength of this material is relatively low; therefore, this material should be used between 2 surfaces that are mechanically held together, for example plate coils on tanks, or supported. This material can run on vertical surface when exposed to temperatures above 149 C (300 F). See SES N01-F10 for metal substrate protection required. |
Not an insulating material. This cement is nonhardening and does not require any curing or drying. Requires no surface preparation. Can be applied to rusty and corroded surfaces. The shelf life is indefinite.

Never apply to surface temperatures above 121 C (250 F) or expose to temperatures above 190 C (375 F). Never use in conjunction with fibrous type insulating materials. Exposure to fibrous materials at elevated temperatures can cause auto ignition.
