Winter Shipments

During winter months, freezable materials, like colloidal silica based binders, should be shipped as early as possible in the week to ensure that they are continuously moving to their destination. While this does not guarantee product will not freeze, it reduces the risk associated with shipping over a weekend where product may sit at a freight facility unprotected from freezing temperatures.


To help you ensure that the product you receive has not been damaged, R&R applies a freeze check indicator, which features a check mark in a green circle. Temperature-sensitive liquid is encased in a clear bubble over the check mark. The fluid will turn opaque and the check mark is no longer visible once it has been exposed to subfreezing temperatures.


Note: This does NOT mean that the material in the package has been frozen; it only means the package has been exposed to freezing temperature.


To assist you in reducing the risk of receiving frozen materials and to guide you on the steps to take if you think you have received a frozen shipment, R&R is providing you with all the resources you need in one document. To view or download the document, click below.
